Underground Utility Contractor in Naperville, IL

Naperville sits mainly in DuPage County and extends into a neighboring county. The city has an estimated 153,124 residents (2024 Census estimate) on roughly 39 square miles of land, and underground work there ranges from single service lines at homes to utility packages for commercial sites.

Residential streets and commercial campuses

In residential neighborhoods, the typical underground problem is a single line: a water service that leaks, a sewer lateral blocked by roots or broken by settlement, a storm connection that no longer drains. Those jobs are small in length but sensitive in place, with mature trees, finished driveways and landscaped yards in the way. Hydro excavation can confirm where a line runs before anything is dug, and directional drilling can sometimes carry a replacement beneath a driveway instead of through it.

On office and retail sites the scale changes. A new tenant may need a larger water service or a separate meter; a parking lot may need storm sewer and inlets rebuilt; a building addition may need power conduit brought in from a transformer pad. Requests like these usually come from developers and general contractors with plans attached, which speeds up the review.

Locates and paperwork

JULIE, the Illinois one-call center, receives locate requests before excavation so that buried utilities are marked. Naperville's location in two counties means the exact address matters for permits and inspections; we will also ask whether the work is on private property, in a public right-of-way or both. A copy of any approved plan sheet showing the line is helpful too.
